Active clinical trials for "Hepatitis C"

This randomized, cross-over, open label study will compare the tolerability and handling of application of peginterferon alfa-2a [Pegasys] by autoinjector versus pre-filled syringe in patients with chronic hepatitis C, either on treatment with peginterferon alfa-2a for at least 12 weeks or treatment-naïve for peginterferon alfa-2a. Patients will be randomized to self-injection of 180mcg peginterferon alfa-2a once a week using either an autoinjector or a prefilled syringe for 3 weeks, then switch to use the other method of injection for another 3 weeks. Anticipated time on study treatment is 6 weeks. Target sample size is <100 patients.

The purpose of this study is to evaluate the effect of steady-state (constant concentration of medication in the blood) TMC435 (150 mg, once a day) on the steady state pharmacokinetics (what the body does to the medication) of R- and S-methadone.

The current Standard of Care (SOC) for chronic HCV infection, which is pegylated interferon-alfa as combination therapy with ribavirin for 24-48 weeks of treatment, is effective in only part of the patients and is often associated with severe adverse effects leading to discontinuation of treatment and dose modifications. A number of compounds with direct activity are currently under clinical development, incl. BI 201335. BI 201335 works by preventing the Hepatitis C virus from replicating by binding to the HCV protease (enzyme). The main purpose of this clinical trial with BI 201335 is to see how well BI 201335 works and how safe BI 201335 is to use daily in combination with PegIFN and RBV in HCV infected patients

The purpose of the study is to investigate if the duration of treatment of hepatitis C with pegylated interferon and ribavirin can be individualized on the basis of how fast the hepatitis C virus concentration in the blood decreases, and if this is more cost-efficient than standard treatment.

The investigators will evaluate the efficacy of high dose vitamin C in chronic hepatitis patients whose serum liver enzymes are elevated more than upper limit.

This is a research study to evaluate the safety, tolerability and anti-viral activity of GS-9669 in patients with Hepatitis C infection.

The purpose of this study is to estimate the rate of sustained virologic response (SVR) SVR12, where SVR12 is defined as HCV RNA < LOQ (detectable or undetectable) 12 weeks post-treatment in Genotype 1 & Genotype 4 treatment naive patients, and Genotype (GT1) infected patients who are prior null responders to pegIFN/ribavirin

This study is a Phase I open label drug interaction study to evaluate the effect of omeprazole and ritonavir on GSK2336805.

The purpose of this study was to evaluate the efficacy, safety and pharmacokinetics of ABT-450/r when given together with ABT-267 and with and without RBV in treatment-naïve participants with genotype 1, 2 or 3 chronic HCV infection.

The purpose of this open label study is to evaluate the safety and efficacy of daclatasvir plus pegylated interferon-alfa 2a and ribavirin in untreated hepatitis C virus in patients coinfected with HIV
